Analysis of abundances and growth of Indo-Pacific tarpon fish ( Megalops cyprinoides) on the estuary of leidong river North Labuhanbatu Regency

Abstract

Leidong river flow is deriving from the Kualuh river basin as the largest river in Labuhanbatu District. The Leidong stream is possibly a water space with changed human exercises which has the potential to cause contamination and disturbance of oceanic biota. The purposes of this study were to figure out fish abundances and the growth of tarpon fish (Megalops cyprinoides) in the Leidong River, North Labuhanbatu District. The highest fish abundance was at station one which was 6 ind/m2, followed by stations 3 and 2 which were 5 and 4 ind/m2. The length and weight estimation of the catched angle at each station demonstrated the development of the tarpon fish with the esteem of b> 3 which is a positive allometric and the value of the condition factor of each K> 1, where this indicates that the condition of the fish in the estuary of the Leidong river morphologically can be said to have good plumpness.
